Hello,

I have a problem with iterating over all edges of a 3D mesh complex. I use
the finite_edges_iterator from the
CGAL::Mesh_complex_3_in_triangulation_3::Triangulation class, but this
iterator returns not only the internal edges but also edges outside the
tetrahedron mesh. 

for (Triangulation::Finite_edges_iterator it = tr.finite_edges_begin(); it
!= tr.finite_edges_end(); ++it) {
        start = it->first->vertex(it->second)->point();
        end = it->first->vertex(it->third)->point();
//...
}

Is there a way to iterate over the internal edges only (those of the
tetrahedra)?

Thanks in advance
